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
