Jack spent of 1/3 her money on a pack of pens 1/2 of her money on a pack of markers and 1/8 of her money on a pack of pencils. what fractions of her money is left. |
|
Answer» The fraction of the amount of money that Jing had left is The fraction of the amount of money Jing spent on the PACK of pens = The fraction of the amount of money she spent on a pack of marker = The fraction of the amount of money she spent on a pack of pencils = The fraction of the money left = 1 Further Explanation One way to determine the total fraction of the amount of money she spent = the fraction of the money left - the fraction of the amount she spent on pack of pens + fraction of the amount spent on marker + fraction of the money she spent on pencils Firstly, WITHOUT the fraction of the money left, we have: = + + = + + , it ALSO the same as = (8+12+3) / 24 (24 is the lowest common denominator) = Since the fraction of the money left = 1 Therefore we have: = 1 – = (24 x 1) – (23 x 1) / 24 (24 is the smallest number that can divide the denominators) Therefore we have: = 24 – 23 / 24 = . Therefore the fraction of the amount that Jing has left is . Notably, we solve this question using the BODMAS rule. |

Answer» Step-by-step explanation: (1) 5.3 cm Steps of construction: 1. Draw line segment AB = 5.3 cm. 2. With A as centre and radius more than half of AB, mark two arcs, one above and other below the line AB. 3. With B as centre and same radius, draw two arcs cutting the previous DRAWN arcs and name the point of INTERSECTION as X and Y. 4. Join XY and name the point where this line cuts AB as point P. XY is the PERPENDICULAR bisector of AB. |

In the given figure “P” is a midpoint of BC, write the formula to find the co- ordinate of P ? |
|
Answer» Answer: Given A △ABC in which P is the mid-point of BC, Q is the mid-point of BC, Q is the mid-point of AP, such that BQ produced MEETS AC at R To PROVE RA= 3 1
CA Construction Draw PS||BR, meeting AC at S. Proof In △BCR, P is the mid-point of BC and PS||BR. ∴ S is the mid−point of CR. ⇒ CS=SR In △APS, Q is the mid-point of AP and QR||PS. ∴ R is the mid−point of AS ⇒ AR=RS From (i) and (ii), we get AR=RS=SC ⇒ AC=AR+RS+SC=3AR ⇒ AR= 3 1
AC= 3 1
