25.	How to turn numbers into a ratio
Answer» Answer: If you want to know how to make a ratio, just follow these STEPS. Step-by-step explanation: 1. Use a symbol to denote the ratio To INDICATE that you're using a ratio, you can use the division sign ( / ), a colon ( : ), or the word to. For example, if you wanted to say, "For every five men at the party, there are three women," then you could use any of the three symbols to state this. 2. Write the first given quantity to the left of the symbol. Write down the quantity of the first item before the symbol of your choice. 3. Write the SECOND given quantity to the right of the symbol. After you've written the first given quantity followed by the symbol, you should write the second given quantity, along with its units. 4. Simplify your ratio (optional). You MAY want to simplify your ratio to do something like scale down a recipe. If you're using 20 g of FLOUR for a recipe, then you know you'll need 8 g of sugar, and you're done. But if you'd like to scale down the ratio as much as possible, then you'll need to simplify it by writing the ratio in its lowest possible terms. You should use the same process as you would use to simplify a fraction. To do this, you have to find the GCF, or the greatest common factor, of both quantities, and then see how many times that number fits into each given quantity. 5.Turn the ratio into a percentage (optional). If you'd like to turn the ratio into a percentage, you just have to complete the following steps: • Divide the first number by the second number. Ex: 5/2 = 2.5. • Multiply the result by 100. Ex: 2.5 * 100 = 250. • Add a percentage sign. 250 + % = 250%. • This indicates that for every 1 unit of sugar, there is 2.5 units of flour; it also means that there is 250% as much flour as there is sugar.

26.	In the given fig AB diameter of a circle AC 6 cm and BC 8 cm find the area of the shaded portion
Answer» Answer: GIVEN: AB is the diameter =d of a CIRCLE. ΔABC has the diameter AB as base & the point C is on the circumference. AC=6 cm and BC=8 cm. To find out: AREA of shaded portion in the given circle. Solution: ∠ACB=90 o since ΔABC has been inscribed in a semicircle. ∴ΔABC is a right one with AB as hypotenuse ...(i) So, applying Pythagoras theorem, we have AB= (AC) 2 +(BC) 2 = (6) 2 +(8) 2 cm=10 cm=d. ∴ The RADIUS of the given circle = 2 d = 2 10 cm=5 cm. i.e The Area of circle =πr 2 =3.14×5 2 cm 2 =78.5cm 2 . Again, Area of ΔABC= 2 1 ×AC×BC (by i) = 2 1 ×6×8cm 2 =24cm 2 . Now, Area of shaded region = Area of circle − area of ΔABC =(78.5−24)cm 2 =54.5cm 2 .

AC=6 cm and BC=8 cm.

To find out:

AREA of shaded portion in the given circle.

Solution:

∠ACB=90

34.	A alone can do a piece of work in 8 days. A and B together can finish the same in 6 days. if B alone is doing the work,how long will he take?
Answer» Answer Given A alone can do a PIECE of work in 8 DAYS A and B together can finish the same in 6 days Find Time required by B to finish the work Solution Let B takes "B" days to finish the work alone Now , ONE day work of A alone Given that , A alone can do a piece of work in 8 days Thus , => 1/8 One day work of B alone We assumed B to finish the work in B days Thus , => 1/B One day work when A and B work together Given that, A and B together can finish the same in 6 days Thus , => 1/8 + 1/B = 1/6 => 1/B = 1/6 - 1/8 => 1/B = (4 - 3)/24 => 1/B = 1/24 => B = 24 Hence B will take 24 days to finish the work alone

A alone can do a piece of work in 8 days. A and B together can finish the same in 6 days. if B alone is doing the work,how long will he take?

Answer»

Answer

Given

A alone can do a PIECE of work in 8 DAYS
A and B together can finish the same in 6 days

Find

Time required by B to finish the work

Solution

Let B takes "B" days to finish the work alone

Now ,

ONE day work of A alone

Given that , A alone can do a piece of work in 8 days

Thus ,

=> 1/8

One day work of B alone

We assumed B to finish the work in B days

Thus ,

=> 1/B

One day work when A and B work together

Given that, A and B together can finish the same in 6 days

Thus ,

=> 1/8 + 1/B = 1/6

=> 1/B = 1/6 - 1/8

=> 1/B = (4 - 3)/24

=> 1/B = 1/24

=> B = 24

Hence B will take 24 days to finish the work alone
