Stanley can build 12 leggo cars in 3 hours.
To see why, you can set up a proportion:
4 cars / 1 hour = x cars / 3 hours
Solving for x:
4/1 = x/3
4 * 3 = x
12 = x
A cantaloupe costs $0.45 per pound. If Jacinta pays $1.80, how many pounds did the cantaloupe weigh?
*

3 pounds
4 pounds
5 pounds
6 pounds
Jacinta paid $1.80, and since the cantaloupe cost $0.45 per pound, we can set up the equation:
$0.45/pound x = $1.80
Solving for x, we get:
x = $1.80 ÷ $0.45/pound
x = 4 pounds
Therefore, the cantaloupe weighed 4 pounds.
12/15=?/5
To solve for the missing value, cross-multiply:
12 × 5 = 15 × ?
60 = 15x
Divide both sides by 15:
x = 4
Therefore, 12/15 = 4/5.

A survey shows 6/20 people prefer green apples over oranges. What percent of people in the survey prefer apples?
*

20%
30%
40%
15%
6/20 can be simplified to 3/10 or 0.3 as a decimal.
To convert this to a percentage, we can multiply by 100:
0.3 x 100 = 30%
Therefore, 30% of people in the survey prefer green apples.
Calculate the discount of a $160 bicycle that’s on sale for 40% off. The discount is ______ .
*
$55
$96
$32
$64
To calculate the discount, we can first find 40% of the original price:
40% of $160 = 0.4 x $160 = $64
Therefore, the discount on the bicycle is $64.
) Order from LEAST to GREATEST: 4/50, 25%, 22/100, 0.3
*
4/50, 22/100, 25%, 0.3
0.3, 25%, 4/50, 22/100
22/100, 4/50, 25%, 0.3
4/50, 22/100, 25%, 0.3 is the correct order from least to greatest:
- 4/50 can be simplified to 2/25 or 0.08 as a decimal.
- 22/100 can be simplified to 11/50 or 0.22 as a decimal.
- 25% can be written as 0.25 as a decimal.
- 0.3 is already in decimal form.
So the ordered list is:
4/50 = 0.08
22/100 = 0.22
25% = 0.25

A notebook costs $1.25 and has a 6% tax added on. Calculate the TOTAL cost of the notebook including tax. (*Round to the nearest dollar and cents)
*
$1.27
$1.33
$2.06
$2.25
Never submit password
To calculate the total cost including tax, we can first find the amount of tax:
6% of $1.25 = 0.06 x $1.25 = $0.075
Then, we can add the tax to the original price:
$1.25 + $0.075 = $1.325
Rounding this to the nearest cent, we get:
$1.33
Therefore, the total cost of the notebook including tax is $1.33.
