Answer:
1%
Step-by-step explanation:
We need our two numbers to have the same units. Since one number is in cents and the other is in dollars, we should change one of them. It could be either one.
Both numbers in cents:
50/4000
OR, both numbers in dollars:
.50/40.00
Either of these will work. Divide, you will get a decimal answer. Then multiply by 100 to change to a percent.
50÷4000 (OR .5/40)
= 0.0125
times by 100
0.0125 × 100
= 1.25% but the directions said to round to the nearest whole number, that's 1%
The correct answer is the third one.
However, i would suggest you to remember the following simple rule:
2100 calories
We find this by multiplying 600 times 3.5
An easy way to do this is multiplying 600 times 3 (1800) and the adding half of 600 (300) to your number for the final number of 2100 calories.
4×2=8. 100×2=200
8% out of 200
so
4=8 if you have double, 200
