Question

solve the answer correctly​

Answer 1

Answer:

a) 4/5 b) 8/10

Step-by-step explanation:

a) let a be the fourth number

56/70 = 4/a

cross multiplying

56 x a = 70 x 4

a = 70 x 4/56 (dividing by 4)

a = 70 x 1/14

a = 70/14 (dividing by 14)

a = 5

The equivalent fraction of 56/70 for numerator 4 is

4/5

b) let a be the fourth number

56/70 = a/10

cross multiplying

56 x 10 = 70 x a

56 x 10/70 = a (dividing by 10)

56 x 1/7 = a

56/7 = a (dividing by 7)

8 = a

a = 8

The equivalent fraction for 56/70 for denominator 10 is

8/10
