Answer:

24+40=8(3+5)

30+40=10(3+4)

30+42=6(5+7)

Step-by-step explanation:

Look at 24 and 40 and determine the biggest number that goes into both of these numbers. Greatest(biggest) common(same) factor(number that goes into another number). Sometimes you can find the prime factorization to do this, or there's a method of listing factors. Both of these numbers are products found in a regular times table. You can run the factors using mental math to find the biggest one.

You consider the factors of 30 and 40. 10 is the biggest number that goes into both.

And 30 and 42, 6 goes into both.

The numbers that go inside the parentheses are the other factors of the two numbers you're given.

24 is 8×3. 8 is the common factor. 3 goes inside the parentheses.

40 is 8×5. 8 is the common factor. 5 goes inside the parentheses.
