Question

How do you guys answer this grade 6 math I need an explanation till tomorrow​

Answer 1

12 11/60

Explanation:

Answer 2

20 ¹¹/₆₀

Explanation:

First, separate the fractions and the whole numbers, then combine the whole numbers:

`(28(3)/(5) -10(2)/(3) )+2(1)/(4)\\(28-10+2)+((3)/(5) -(2)/(3)+(1)/(4))\\20+((3)/(5) -(2)/(3)+(1)/(4))`

Next, find the least common denominator.

In this case, LCD = 3 × 4 × 5 = 60.

Write each fraction with the new denominator:

`(3)/(5)* (12)/(12) =(36)/(60) \\\\(2)/(3)* (20)/(20) =(40)/(60) \\\\(1)/(4)* (15)/(15) =(15)/(60)`

Now perform the addition and subtraction.

`20+((3)/(5) -(2)/(3)+(1)/(4))\\20+((36)/(60) -(40)/(60)+(15)/(60))\\20+((36-40+15)/(60))\\20+((11)/(60))\\20(11)/(60)`

11/60 doesn't reduce, so the final answer is 20 ¹¹/₆₀.
