Ivan finished 4/5 of his math homework problems and all 3 questions for his science homework before dinner. if he finished a total of 43 problems before dinner, what is the total number of math homework problems he was assigned?

50 Is the correct answer  

Step-by-step explanation:

Because 4/5 = 0.8 an if you divide 50 by 0.8. 50/0.8 = 40.

Also cause I took the test and got it right. It said this was correct.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
