Question

2. Two numbers are in the ratio 7 : 9. If their sum is 320, find the numbers.
3. Simplify the given ratios in lowest form.
a) 2 years : 4 months
b) 15 mins : 3hours

Answer 1

Step-by-step explanation:

let the numbers be x say

then the ratio becomes 7:9 = 7x:9x

given that,

sum of two numbers is 320

hence,

7x+9x = 320

16x = 320

x = 320/16

x = 20

therefore, 7x = 7*20 = 140

9x = 9*20 = 180

2 years : 4 months

24 months : 4 months

6 months : 1 month

6 : 1

15 min : 3 hours

15 min : 180 min

1 min : 12 min

1 : 2
