1.	Multiply:(i) (7/11) by (3/5)(ii) (3/5) by 25(iii) 3 (4/15) by 24(iv) 3 (1/8) by 4 (10/11)
Answer» (i) Given (7/11) by (3/5) We have to multiply the given number (7/11) × (3/5) = (21/55) (ii) Given (3/5) by 25 (3/5) × 25 = 15 [dividing 25 by 5] (iii) Given 3 (4/15) by 24 First convert the given mixed fraction to improper fraction. (49/15) × 24 = (1176/24) = 78 (2/5) (iv) Given 3 (1/8) by 4 (10/11) First convert the given mixed fraction to improper fraction. (25/8) × (54/11) = (1350/88) = (675/44) = 15 (15/44) (7/11)(3/5)=(21/55) (3/5)25=15 (49/15)24=78.4 (25/8)(54/11)=15.3409091

Answer»

(i) Given (7/11) by (3/5)

We have to multiply the given number

(7/11) × (3/5)

= (21/55)

(ii) Given (3/5) by 25

(3/5) × 25 = 15 [dividing 25 by 5]

(iii) Given 3 (4/15) by 24

First convert the given mixed fraction to improper fraction.

(49/15) × 24

= (1176/24)

= 78 (2/5)

(iv) Given 3 (1/8) by 4 (10/11)

First convert the given mixed fraction to improper fraction.

(25/8) × (54/11)

= (1350/88)

= (675/44)

= 15 (15/44)

(7/11)*(3/5)=(21/55)

(3/5)*25=15

(49/15)*24=78.4

(25/8)*(54/11)=15.3409091
