1/4 is 2 8ths, so it is 2X3 or 6. six eights is equal to three quarters
two eights make one quarter so it takes threes times as many to make three quarters. So, 6 eights make three quarters. ( A eighth of a dollar is called a bit so 2 bits is a quarter and 6 bits is 75 cents. There is an old song that ends with "Shave and a haircut - six bits.)
3 eights would be 24. Dividing by 4, you will get 6.
To make this comparison, you must find common denominators for both fractions. Let for be the common denominator. If we divide the numerator and denominator of the first fraction (4/8) by 2, we get 2/4. Comparing 2/4 with 3/4, the second fraction is bigger because 3 is greater than 2. Also, four eights simplifies to one half, which is less than three quarters.
12 quarters will make $3
4 quarters go into one dollar. So 12 quarters = 3 dollars.
There are 4 quarters in one dollar. Three of them then have 3X4 =12 quarters. There are three more in seventy five cents (0.75). All together there are 12+3 =15 quarters.
You can make 90 cents with three quarters and three nickels. (3 x 25) + (3 x 5) = 90 cents.
The final answer would be three and three-eighths. Here's how to solve it mentally.You have to set their denominators [bottom numbers] equal. So, keep seven eights, since two ["half"] goes into eight, but you must make 2 and a half into 2 and four eights, because four is half of eight. Pretend for a minute that the four eights isn't there. So, 2 and seven eights. Then, add one from the four eights, so that it will now be 3., and so that the four eights is now three eights. So, 3 and three eights.Sorry. I'm not very good at explaining, but I hope that helped. ^^"
