Answer:
15
Step-by-step explanation:
5 divided by 1/3 is the same as if you flip the denominator meaning 5 x 3 which is 15
Answer: 5
Step by Step Explanation:
5x + 4x = 720
9x = 720 (divide by 9)
X= 80
In order to get the bigger ratio, which is 5, you would substitute x for 80. (I'm bad at explaining)
Work:
5(80)= 400
7 • 5
Multiplication is basically repeated addition. So to convert repeated addition to multiplication, we take the number being added (7) and multiply it be the number of addens (5). Therefore, 7+7+7+7+7 = 5 • 7
