Answer:
A. 7.5
B. 10
Step-by-step explanation:
The first one is 3x2 + half of 3x1 for 6 + 0.5*3 total.
The second one is 3x2 + 4 times half a 2x1 for 6 + 4 * 0.5 * 2 = 10
Answer:
1 hour = 60 minutes
20 minutes = 1/4 of 60 minutes, which means 60 minutes = 4/4
when you write ratios, the larger number goes first - 60 minutes out of 15 minutes = 4/1, so the ratio in simplest form is 4:1
