Here’s how you would work it out
The expression for five groups of a number added to seventeen.
Let the number be X
Five groups of the number will be 5X
The required expression will be
5(X) +17
Multiplicand is the number that gets multiplied, multiplier is the number that you are multiplying by, product is the result of mulptiplication multiplicand by multiplier.
Let a be a multiplicand, b be a multiplier and c be a product, then
a·b=c.
To check the correctness of the answer to a multiplication example, you should divide the product c by the multiplier b:
c÷b=a.
Answer: correct choice is A.
2 1/2 = 2.5
12 1/2 = 12.5
This means you can calculate how may times it goes in by dividing it and rounding the number down:
12.5 / 2.5 = 5
*5 can not be rounded down so it stays the same
This means that 2 1/2 goes into 12 1/2 5 times. Hope this helps! :)
