Answer 1

Answer: I wouldn't say that. It looks to me like you've absolutely got it ... almost.

A). Your fraction is correct. But it's not in simplest form like they want it.
Reduce 18/45 to simplest form. Hint: Divide top and bottom by 9 .

B). They want the percentage that's the same as 18/45 .
Do you remember how to change a fraction to percent ?
A fraction is just a short way to say "division".
" 18/45 " means " 18 divided by 45 ".
Do the division. To change the quotient into percent, multiply it by 100 .
(Same as moving the decimal point 2 places to the right.)
Round it the nearest whole number, if it isn't already a whole number.

C). Again, your fraction is correct, but it isn't in simplest form.
Reduce 27/45 to simplest form. Hint: Divide top and bottom by 9 again.

D). Change this fraction to percent, just like you did for the female fraction.
(Do the division that the fraction says, and multiply the quotient by 100.)
(Round to the nearest whole number percent if it isn't already.)

You already did the technical stuff. I just added some mechanical things.

At the market, 555 light bulbs cost \$9$9dollar sign, 9.
How much do 777 light bulbs cost?

Answers

Question:

At the market, 5 light bulbs cost $9. How much do 7 light bulbs cost?

Answer:

Cost of 7 bulbs is $ 12.6

Solution:

Given that,

5 light bulbs cost $ 9

Find the cost of 1 bulb

Cost of 1 bulb is found by dividing the cost of 5 bulbs by 5

$cost\ of\ 1\ bulb = \frac{\text{cost of 5 bulbs}}{5}\n\ncost\ of\ 1\ bulb = (9)/(5)\n\ncost\ of\ 1\ bulb = 1.8$

Thus cost of 1 bulb is $ 1.8

Find the cost of 7 bulbs:

$cost\ of\ 7\ bulbs = 7 * \text{cost of 1 bulb }\n\ncost\ of\ 7\ bulbs = 7 * 1.8\n\ncost\ of\ 7\ bulbs = 12.6$

Thus cost of 7 bulbs is $ 12.6

Answer:

7 bulbs equals 12.6
