how to write the expression 25 less than 12 groups of 15?
25-12(15)... is this correct
Okay so whenever we have the phrase "less than" we know that in the end we must subtract from what is in front of the "less than"
therefore your expression would be 12*15-25
25-12(15)
Yes
Well, you almost got it! But remember, when dealing with multiplication, we need to prioritize it before subtraction. So the correct expression would be: 12(15) - 25.
To write the expression "25 less than 12 groups of 15," you can start by representing "12 groups of 15" as a multiplication expression.
The number of groups, 12, is being multiplied by the value in each group, which is 15. So, you can write it as 12 * 15.
To indicate "25 less than" that expression, you subtract 25 from it. Therefore, the complete expression would be:
12 * 15 - 25
So, your expression, 25-12(15), is not correct. The correct expression should be 12 * 15 - 25.
