Answer:
10.8
Step-by-step explanation:
The GCF is the greatest common factor.
Find the factors for 45, 90, and 75;
45: 1, 3, 5, 9, 15, 45
90: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
75: 1, 3, 5, 15, 25, <span>75
Now find the biggest factor they have in all, which is 15.
Hope this helps. </span>
I do suppose that you refer to adding these quantities:
6/1 + 21 = 6 + 21 = 27
<span>and
6/10 + 21
</span>= 3/5 + 21
= 3/5 + 105/5
<span>= 108/5</span>
Answer:
42
Step-by-step explanation:
x+(x+13)=71
2x+13=71
2x=71-13
2x=58
x=29 (alvin)
71-29=42 (elga)
A ratio is the relationship between two numbers.
Probably the easiest way to write a ratio is in the form of a fraction.
A fraction IS a ratio.
It means (the top number) divided by (the bottom number), and
that's the ratio between them.
