Question

the sum of one fourth of a number and 2 1/5 is 3. find the number
​

Answer 1

Answer:

the number is 16/5

Step-by-step explanation:

Given,

1/4 of y + 2 1/5 = 3

1/4 × y + 11/5 = 3

1/4 × y = 3/1 + 11/5 (LCM of 5,1 = 5)

           = (3 × 5 - 11 × 1)/5

           = (15-11)/5

1/4 × y  = 4/5

y = 4/5 × 4/1

y = 16/5
