lf you added a fifth of one and a quarter to one and a quarter, what would the answer be ? .....
The answers is 1 1/2
have tries
0.2 + 0.25 + 0.75 = 1.20 or 1 1/5 ????
0.2 + 0.75 + 1 + 0.25 = 2.20 ???
Please help!
fifth of one and a quarter:
(1/5)*(1 1/4)
= (1/5)*(5/4)
= 1/4
one and a quarter:
1 1/4
= 5/4
adding them,
1/4 + 5/4
= 6/4
= 3/2
= 1 1/2
Hope this helps :)
or, going at it from another way,
1/5 + 1 = 6/5
(6/5)(5/4) = 6/4 = 1 1/2
To calculate the sum correctly, you need to make sure you are adding fractions instead of decimals. Here's how you can correctly add a fifth of one and a quarter to one and a quarter:
First, let's convert the decimals to fractions:
- One and a quarter can be written as 1 1/4 or 5/4.
- A fifth of one and a quarter can be calculated by multiplying 1/5 by 5/4. This gives us 1/5 * 5/4 = 5/20 or 1/4.
Now, let's add the fractions together:
5/4 + 1/4 + 5/4 = (5 + 1 + 5) / 4 = 11/4.
To convert this fraction to a mixed number, we divide the numerator (11) by the denominator (4):
11 ÷ 4 = 2 with a remainder of 3.
Therefore, the answer is 2 3/4.
