Question

Ami and Dan are going to bake a cake. They need two and a half cups of flour. Ami has 5/4 cups of flour, and Dan has 4/3 cups of flour. Do they have enough flour to bake the cake? *

Answer 1

They have enough.

`2(6)/(12) <2(7)/(12)`

Explanation:

`(4)/(3)+ (5)/(4)`

4 = 2 × 2

3 = 3 × 1

LCM of 4 and 3

= 2 × 2 × 3 × 1

= 12

`4((4)/(3))+ 3((5)/(4))`

`(16)/(12)+ (15)/(12)`

`(31)/(12) =2(7)/(12)`

`2(1)/(2) =2(6)/(12)`

`2(6)/(12) <2(7)/(12)`
