At an assembly 7 out of the first 10 students who entered the gym were carrying a backpack. Based on this information, if 700 students were already at the assembly, how many students can be expected to be carrying a backpack?

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
