What is the HCF of 15 27 and 30?
3. 15/3 = 5. 27 / 3 = 9. 30/3=10
What is the answer to 9 over 10 minus 8 over 15?
Find the least common denominator of 10 and 15, which is 30. If 15 is doubled to 30, the 8 over it must be doubled to 16. If 10 is tripled to 30, the 9 over it must be tripled to 27. 27 over 30 minus 16 over 30 is 11 over 30.
What is nine tenths minus four fifteenth?
To subtract fractions, we need a common denominator. The least common multiple of 10 and 15 is 30. So, we rewrite 9/10 as 27/30 and 4/15 as 8/30. Subtracting, we get 27/30 - 8/30 = 19/30. Therefore, 9/10 - 4/15 = 19/30.
What is 9 over 10 minus 13 over 30?
9/10 - 13/30 = 27/30 - 13/30 = 14/30 = 7/15
Which is bigger thirteen fiteensths or nine tenths?
Either convert both to decimal, or convert both to a common denominator.The common denominator is 30. 13/15 = 26/30, and 9/10 = 27/30.A comparison of the numerators (27 > 26), so 27/30 is bigger [9/10]
