Answer:
12.5 miles per hour
Step-by-step explanation:
This is a fraction equal to
25 miles ÷ 2 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 2
<u>25 miles </u>÷ 2
2 hours ÷ 2
<u>12.5 miles</u>
1 hour
= 12.5 miles per hour

Answer:
See answers below
Step-by-step explanation:
Given the following ratios. We are to express them in their simplest forms
15:12
= 15/12
= (3*5)/(3*4)
= 3/3 * 5/4
= 5/4
b) 42:1
= 42/1
= 42
Given that 2:x :: 4:6
2/x = 4/6
Cross multiply
4x = 2*6
4x = 12
x = 12/4
x = 3
Hence the value of x is 3
Given:
