about 25% of the students in mr. goodman's class got an A on their last math test. of those, 50% are girls. the class has 12 girls and 16 boys. is it reasonable to say 6 girls got an A on the test?

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
