Q: What must be added to three eights to make a whole?

Write your answer...

Eight one eights make a whole.

eight eghts make a whole

3 eights would be 24. Dividing by 4, you will get 6.

Eight sevenths of them.

Eight eighths make up a whole unit.

1

eight of them make a whole teaspoon

Six.

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.)

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. ^^"

5/5 is a whole, therefore is you have 3/5 you need another 2/5 to make it 5/5.

Eight of them.

1/4 is 2 8ths, so it is 2X3 or 6. six eights is equal to three quarters

four fifths must be added to make it whole

What must be added to 3 tenths to make 1 whole

7/10 must be added to 3/10 to make 1 whole.

Five-ninths must be added to four-ninths to make a whole.

7/10 must be added to 3/10 to make a whole number, 1.

11 whole eights, with 6 left over. The 6 will make 3/4 of another eight.

Probably 3*8 = 24 and 2+4 = 6

Two fifths, this is because 5 fifths is the whole and if you already have 3 fifths you just need 2 more to make 5.

0.997

three if the question was How many 1/3 make a whole

Three-fourths and one-fourth make a whole.

Three thirds make up a whole.
