Question

Brandon used 1 2

Answer 1

Answer:

$5\dfrac{1}{2}\ \text{kg}$

Step-by-step explanation:

Plant food used on strawberry plants is

$1\dfrac{2}{3}\ \text{kg}=\dfrac{5}{3}\ \text{kg}$

Plant food used on tomato plants is

$\dfrac{1}{4}\ \text{kg}$

Feeding the strawberry plants two times means

$\dfrac{5}{3}+2\times\dfrac{5}{3}=\dfrac{5}{3}+\dfrac{10}{3}\\ =\dfrac{15}{3}=5\ \text{kg}$

Feeding the tomato plants one more time means

$\dfrac{1}{4}+\dfrac{1}{4}=\dfrac{2}{4}\\ =\dfrac{1}{2}\ \text{kg}$

The plant food he will need is $5+\dfrac{1}{2}=5\dfrac{1}{2}\ \text{kg}$
