What is proportion?

A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls. 0.25 are boys (by dividing 1 by 4.

Relating the example with the question , for every 6, N100 notes there is 1, N10 notes . This means the ratio of N100 note to N10 note is 6:1

Therefore for every N600 there will be 10N

following the trend, for every N1200 there will be N20. for every N1800 there will be N30 and for every N2400 there will be N40

The addition of 2400+40= 2440

This means that the sum of N100 is 2400

Therefore the number of N100 is 2400/100= 24 notes

Isaac’s family took a cab to a concert. The bill came to a total of $43.50. The family wants to tip the driver at least 20%. Which tip amounts would be sufficient? Select all that apply.

$7
$8
$9
$10
$11

Answers

Answer:

The option d is the correct answer

to find a percentage of something we were taught this method

%% x
—— • ——
100 total price

you then want to multiply the total price by the percentage and then divide by 100

so in this case

20 x
—— • ——
100 $43.50

20•43.50=870

870/100= 8.7

so i believe 9,10,11 would all be correct.
