The total weight of pineapple and an orange is 1,160 g or 1.16 kg
Further Explanation
From the math word problem above we can get some information and create some equations. Let's say
A pineapple = x
An orange = y
\(\boxed {x = 7y\ }\\ \boxed {x = 870 g + y }\)
From those equation we can find the value of variable y
\(\boxed {7y = 870 + y }\\ \boxed {7y-y = 870 }\\ \boxed {6y = 870 }\\ \boxed {y=145 }\)
After we get the variable y, the next step will be calculate the variable x by substitute y into one of the above equation :
\(\boxed {x = 7y }\\ \boxed {x= 7 \times\ 145 }\\ \boxed {x=1015 }\)
so, the a pineapple weights is 1015 g, and an orange weights is 145 g
Let's answer the question!
a. The total weight for a pineapple and an orange in g:
\(\boxed {1015 g + 145 g = 1160 g }\)
b. The total weight for a pineapple and an orange in kg:
We need to convert the total weight from g to kg
\(\boxed {1 kg = 1000 g }\\ \boxed {1 g= \frac{ 1 }{1000} kg }\\ \boxed {1160 g = ..... kg? }\\ \boxed {= \frac{1160 g}{1000} }\\ \boxed {=1.16 kg} }\)
In doing conversion there are 3 easy three steps to follow:
- write the conversion in fraction
- multiply/divide
- cancel any units that are both on the top and bottom
