- like 7/5 pizza when you have 1 pizza +2 out of 5 pizza.try to visualise it like this. simple(1 vote)
- “Yes i can. so now as you ...”
Yes i can.
so now as you say 10/5
it is an improper fraction AS THE NUMERATOR (10) is GREATER THAN THE DENOMINATOR (5). it means this fraction is greater then 1, now if we divide 10 by 5 we get 2 as quotient and no remainder, which means 10/5 is 2. now if u wanna put these fractions on the number line. u need to put the number from 0 to 3 on the number line (only for this fraction) and as the denominator is 5, the distance between 2 numbers, for eg. 0 and 1 must have 5 parts, so we need to make 3 whole numbers on number line with 5 parts between all the numbers. so now we have 3*5 = 15 parts total, as we have number 10 we need to mark the first 10 parts, and then u get the answer, which is 2 or 10/5(2 votes)

- What is the answer of 43+30 on a number line?(2 votes)
- 43 = (40+3), and 30 = (3x10). So, 3x10 + 40 + 3 = 73(5 votes)
- wat if it is infinity over 0(3 votes)
- infinity over 0 is undefined, because by what number will you multiply to reach infinity? No! You can't.(3 votes)

- [Voiceover] We're on the fractions on the number line exercise on Khan Academy, and they ask us to move the orange dot to three-fourths on the number line. Change the number of divisions to create tick marks on the number line. Let's see what's going on here. I have the space from zero to one on the number line. If I want to move it to three-fourths, what I would first want to do is divide the space between zero and one into fourths, into four equal sections. I would want to have four divisions here. And there you have it, four divisions. I typed in the number four and have four equal divisions. One, two, three, four. This is going to be a fourth, that's another fourth, that's another fourth, and that's another fourth. What we care about is three-fourths. Once again, that's one-fourth, this would be another fourth, getting us to two-fourths, and then this would be another fourth, getting us to three-fourths. So, there you have it. That is three-fourths on the number line.
