Ratio 5 to 15 in a fraction lowest term

To do this, divide the numerator and denominator by the GCF. In this case, it's 5.

5:15
5 ÷ 5: 15÷5
1:3

Hope this helps!

To solve this ratio, we must first find the GCF, or the Greatest Common Factor, that is, the largest number that fits into both numbers. We can set up a table to compare the factors of each individual number, then identify common factors between the two numbers.

15 |  1  3  5  15
 5 |  1  5

We see that the common factors include 1 and 5, however, 5 is the greatest common factor. Now we can simplify the ratio by dividing both numbers by 5.

5/5  = 1
15/5 = 3

Simplified Ratio: 1:3 (which is 1/3).

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
