The amount ( in kilograms ) of vegetables they harvested in all

EVALUATION

Here it is given that the grade 6 class harvested 3 1/4 kg of tomatoes, 5 3/4 kg of eggplants and 2 1/2 kg of green pepper from their ''Gulayan sa paaralan''.

Hence the total amount of vegetables they harvested in all

$\displaystyle \sf{ = \bigg( \: 3 \frac{1}{4} + 5 \frac{3}{4} + 2 \frac{1}{2} \: \bigg) \: \: \: kg }$

$\displaystyle \sf{ = \bigg( \: \frac{13}{4} + \frac{23}{4} + \frac{5}{2} \: \bigg) \: \: \: kg }$

$\displaystyle \sf{ = \bigg( \: \frac{13 + 23 + 10}{4} \: \bigg) \: \: \: kg }$

$\displaystyle \sf{ = \bigg( \: \frac{46}{4} \: \bigg) \: \: \: kg }$

$\displaystyle \sf{ = \bigg( \: \frac{23}{2} \: \bigg) \: \: \: kg }$

$\displaystyle \sf{ = 11 \frac{1}{2} \: \: \: \: kg }$

Answer 2

Given:

the grade 6 class harvested 3 1/4 kg of tomatoes, 5 3/4 kg of eggplants, and 2 1/2 kg of green pepper.

To find:

how many kilograms of vegetables did they harvest in all?

Solution:

To find how many kilograms of vegetables did they harvest in all, we need to add the given fractions.

$= > 3\dfrac{1}{4} + 5 \dfrac{3}{4} + 2 \dfrac{1}{2}$

$= > \dfrac{13}{4} + \dfrac{23}{4} + \dfrac{5}{2}$

LCM of 4, 4, and 2 is 4

$= > \dfrac{13 + 23 + 10}{4}$

$= > \dfrac{46}{4}$

$= > \dfrac{23}{2}$

Hence, They harvest 23/2 kilograms of vegetables.
