Answer:
$2.5
Step-by-step explanation:
Number of pounds of banana needed = 5 pounds
Cost per pound of banana = 0.50
To solve using place value blocks :
Ignoring the decimal in the cost per pound:
We can first take the product of 5 (Number of pounds of banana) and take cost per pound as 5. Since it is easier to make direct multiplication without decimal.
5 * 5 = $25
Now we can add the one decimal point (in the cost per pound) to our result
Then we have $2.5
Hence, total cost = $2.5
Answer:
37.5 percent
Step-by-step explanation:
Well, there are 25+15=40 total people. Since there are 15 children, the percent is 15/40, which is equal to .375
Because percent is by hundredths, multiply by 100 by moving the decimal to the right twice, and you have a percentage of 37.5.
Answer:
350
Step-by-step explanation:
Answer: It is a 25% increase.
Step-by-step explanation: First lets subtract her new wage from her old wage. 10 - 8 = 2
Next, lets write an percent equation, for p = percent.
2 = p x 8
Basically, we are saying that her new wage will be what percent of her old wage.
Next,
2/8 = p
0.25 = p
Now, multiply 0.25 by 100 to get a percent
0.25 x 100 = 25
So her new wage is a 25% increase from her old wage.
