Question

Pls tell me step wise answer

Answer 1

Answer:

Lets suppose the number is x

Step-by-step explanation:

Now as mentioned lets subtract number from ratio 6:7

6-x:7-x and it should be less than 16:21

now equation becomes

6-x/7-x < 16/21

126-21x <112-16x

126-112<21x-16x

5x>14

x>14/5

x>2.8

The least whole number greater than 2.8 is 3
