Answer: 42
For this situation we will use a ratio to show how many free throws Erin will make. Using the ratio 7:10 represents that Erin will make 7 out of every 10 free throws. You want to know how many free throws she will make if she attempts 60 free throws.
Using ratios we will be able to find how many free throws she will make if she attempts 60.
7:10
14:20
21:30
28:40
35:50
42:60
Basically we kept multiply the right side of the ratio which is 10 by 2 until we were at 60 free throws.
Erin will make 42 free throws if she attempts 60 free throws.
360 meters is the answer as 9 meter in 1st second ,27 meter in 2nd and 81 in 3rd it is in a series of geometric progression ...of 9,27,81 in which 9*3 =27,27*3=81 so next number will be 81*3=243 total distance moved in 4 seconds is 243+81+27+9=360 meters
1)
neverminding how many grams or liters...or whatever unit for now
we know one bag of grass covered 1/6 of the lawn, "a whole" or 1, is 6/6
if 1 bag covers 1/6, to cover 6/6 is just 1/6 +1/6 +1/6 +1/6 +1/6 +1/6 , or 6 bags
2)
one can was enough for 1/4 of the sprayer, a full sprayer is 1 whole or 4/4, so 1/4 + 1/4 + 1/4 + 1/4 or 4 cans
3)
one potato gives enough for 1/3 for a lighbulb, again, 1 whole is 3/3, so 1/3 +1/3 +1/3 , so 3 potatoes
