Question

heyy soo i just started math class and im veryy confused I've tried different things to get to the answer but it didn't work soo can y'all comment some of your ways lol? tonight would be great if possible

Answer 1

yes sure, i learned this before so

1. a. make a proportion here, of percentage. $\frac{225}{250} =\frac{x}{100}$ if you cross multiply and divide you get 90%.

1. b. obviously the empty seats would be 10%.

2. a. proportion again, $\frac{0.90}{6.00} =\frac{x}{100}$ cross multiply then divide you ge 15%

3. 30% in decimal form is 0.3. multiply it then to the total amount, so 0.3 x 15 = 4.5

Answer 2

$1 \: a) \:\frac{225}{250} \times 100 \\ 2b) \: \frac{25}{250} \times 100 \\ 3)0.3 \times 15 \\ \\ 2)0.9$
