Answer:
Choice D
Step-by-step explanation:
3 ÷ 4/5
We need to have 3 of something and divide it into 4/5
This eliminates choices B and C because those have 4/5 of something
Choice A is giving away which is subtracting
Choice D is 3 lbs divide into 4/5 lb groups
4 fractions that are equal to 1/3
1*2/3*2 = 2/6
2/6
1*3/1*3 = 3/9
3/9
1*4/3*4 = 4/12
4/12
1*5/3*5 = 5/15
5/15
Answer:
I am pretty sure the answer is A
Step-by-step explanation:
Let P be the number of kids,
we know P>57
take 1-(1/2)-(1/5)=3/10
therefore 57 is 3/10P
3/7P=57
P=57*7/3=133 is the answer
it would be incorrect if we didnt get a positive integer.
The correct answer is 7. You add five to both sides then divide by three and you get 7 for x
