Answer:
40% decrease
Step-by-step explanation:
This is a decrease since the amount got smaller
To find the percent decrease, take the original amount and subtract the new amount
70-42 = 28
Divide this by the original amount
28/70=.40
Change to percent form by multiplying by 100
.40*100% = 40%
Answer:
6
Step-by-step explanation:
12 divided by 6= 2 and 18 divided by 6=3
The distributive property can help you by allowing you to make smaller, easier divisions from your original quantity.
For example, 176 divided by 8 seems complicated at first. However, by breaking it into smaller pieces via the distributive property, it will be easier to compute.
First, take a smaller number out of 176 that is divisible by 8, like 80. 80 divided by 8 is 10, and you will be left with 96 from the original 176. Another 80 divided by 8 is another 10, and you will be left with 16 from the original 176. 16 divided by 8 is 2. So, now you can add all these results together: 10 + 10 + 2 = 22. 176 divided by 8 is 22.
176/8 = 80/8 + 80/8 + 16/8 = 10 + 10 + 2 = 22.
