Question

write ratios and simplest form
a)80: 112
b) 425:750
c)629:407​

Answer 1

Answer:

5:7

17:30

17:11

Step-by-step explanation:

a) 80:112

We shall first divide it by 2 We get,

= 40:56

Again dividing it by 2,

= 20:28

Again dividing it by 2,

= 10:14

Again dividing it by 2,

= 5:7

We know that 5 and 7 doesn't have any common factor this 5:7 is simplest form of 80:112

b)  425:750

We shall first divide it by 5 We get,

= 85:150

Again dividing it by 5,

= 17:30

We know that 17 and 30 doesn't have any common factor this 17:30 is simplest form of 425:750

c)  629:407

We shall divide it by 37 We get,

= 17:11

We know that 17 and 11 doesn't have any common factor this 17:11 is simplest form of 629:407

Answer 2

Answer:

a)80: 112= 5:7

b) 425:750= 17:30

c)629:407= 17:11
