1x•4x•5x=180
10x=180
10/10x=180/10
X= 18
Changing improper fractions to mixed
form or mixed numbers is a very simple thing. You just have to follow the following:
Then write
Let us have 25/8.
<span><span>
1.
</span><span>Divide the numerator (top
number) by the denominator (number below
the bar). </span></span>
Simply divide 25 by 8.
25 ÷ 8 = n
We can have 3 and 1 as a remainder. So, the
answer will be 3 and 1/8.

like this:</span></span>
3 and 1 (remainder) over 8
(denominator of the given improper fraction).
That is, 3 1/8
Answer:
Step-by-step explanation:
Let the ages be r and m
<u>We have:</u>
<u>Substitute m in the second equation and solve for r:</u>
- m = 117 - r
- 5r = 9 + 3( 117 - r)
- 5r = 9 + 351 - 3r
- 5r + 3r = 360
- 8r = 360
- r = 360/8
- r = 45
<u>Then m is</u>
