Answer:
7 / 2, or 3.5 is between 3 and 4.
28 / 5, or 5.6 is between 5 and 6
9/4, or 2.25, is between 2 and 3.
28 / 5, or 4.6, is between 4 and 5.
Step-by-step explanation:
To multiply a whole number by a fraction, the actual way to do it is to make the non-fraction over one. So, for example, if we were to do this:
2 * (1/2)
Set 2 as 2/1 (because they are equal)
(2/1) * (1/2)
Then, multiply the numerators together and denominators together.
= 1
But, we can also save time and multiply the non-fraction with the fraction's numerator.
2 * (1/2) =
(2 * 1) / 2 =
2 / 2 =
1
Let's apply this to the problems we have.
7) 5 * (7/10)
Multiply 5 and 7.
(5 * 7) / 10 = 35 / 10 = 7 / 2
This is the answer (unless you want it even more simplified, which would either be 3 and 1/2, or 3.5). However to find what numbers it is between, simplify it further.
7/2 = 3.5
7 / 2, or 3.5 is between 3 and 4.
8) 7 * (8/10)
Multiply 7 and 8.
(7 * 8) / 10 = 56 / 10 = 28/5 = 5.6
28 / 5, or 5.6 is between 5 and 6
9) 3 * (3/4)
Multiply 3 and 3.
(3 * 3) / 4 = 9 / 4 = 2.25
9/4, or 2.25, is between 2 and 3.
10) 6 * (4/5)
Multiply 6 and 4.
(6 * 4) / 5 = 23 / 5 = 4.6
28 / 5, or 4.6, is between 4 and 5.
