Answer:
How many kilograms of fruits did she buy in all?
3/4
How many more kilograms of banana than lanzones did she buy?
1/4
For first question:
How many kilograms of fruits did she buy in all?
for this, we need to add 1/2 and 1/4.
1/2 - banana
1/4 - lanzones
1/2 + 1/4
we have to find the LCD of 2 & 4..
! 4 ! we put the 4 as the denominator.
= 2/4 + 1/4
here, is still the same as normal addition.. but it's fraction.
(2 + 1
-------
4)
2+1 = 3
so, we make 3 as the numerator ( upper part).
and the 4 as the denominator (lower part).
=3/4
For second question:
How many more kilograms of banana than lanzones did she buy?
here, we now have to subtract the 1/2 and the 1/4.
1/2 - banana
1/4 - lanzones
(banana - lanzones) (1/2 - 1/4)
1/2 - 1/4
we have to find the LCD of 2 & 4
! 4 ! we put the 4 as the denominator.
=2/4 - 1/4
here, is still the same as normal subtraction.. but it's fraction.
(2 - 1
-------
4)
2 - 1 = 1
so, we make 1 as the numerator ( upper part).
as the numerator ( upper part). and the 4 as the denominator (lower part).
=1/4
