1st: split the 1 shape into 2 shapes. (spit across to where you see one right angle(top), and a trapezoid(bottom)

2nd: now what i did was fill that gap to where the total height is 9 and the total length is 7. ( if you don't want to do that it is fine )

3rd: for the top do 5 times 2 = 10

4th: for the bottom do 4 times 5 = 20

5th: add 10 (top) and 20 (bottom) = 30

Use +,-,x, ÷ and parentheses to connect the numbers 1,3,5 and 7 such that the result is 24.
Alborosie

Answer: (3-1)×(7+5)

Step-by-step explanation:

There are mainly several ways to get 24

- 2×12

- 3×8

- 4×6

- add all of them together

- complicated ones can include large numbers minus another large number

Use try-check-revise, to find the way that fits 24

For this question, we used 2×12, which results in (3-1)×(7+5)

Hope this helps!! :)

Please let me know if you have any questions.
