Answer:
A 4* (7 - 3)
Step-by-step explanation:
Let's do this part by part. First we have "subtract 3 from 7:" this means we are taking 3 out of 7.
7 - 3
Next we have "then multiply by 4." So we need to take the above quantity and multiply the whole thing by 4.
(7-3) x 4
or
4 * (7-3)
The answer is A.
It would be 21 as a percent and 0.21 as a decimal
