Which equation and solution can be used to solve this problem?
Twenty-two less than a number is twenty-four.
The answers are in the picture.
Please help.

D

Step-by-step explanation:

We need to convert these words into mathematical expressions:

- "Twenty-two less than a number"; "less than" indicates that we need to use subtraction, and since it's "twenty-two less than", we have: -22. Let's say the "number" is q. Then, we have -22 of q, which is q - 22.

- "is twenty-four"; "is" in math always means "equal", so we need an equal sign with 24 next to it: = 24

Put this altogether:

q - 22 = 24

The answer is thus D.

Last one

Step-by-step explanation:

Let the number be q

22 less than the number: q - 22

Is 24

q - 22 = 24

q = 24 + 22

q = 46

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
