Round the fraction 7 4/5 to the nearest whole number
1 answer:
The nearest whole number is <span><span>8</span></span>

We can change to a decimal to equal 7.8 by multiplying both our denominator and our numerator by 2 since 5 * 2 =10, which would change our fraction to 
which is the same thing as .8
If we look at 7.8 and want to know if it is closer to 8 or 7, we just remember that when rounding, if it is 5 or above, you round up, anything else, you leave the number in front of it like it is. .8 is above 5 so we round 7 to the whole number 8. So, our answer is 8
