Answer:
The small box is 125g and the larger is 375g.
Explanation:
Let x be the weight of one box, if the larger box is 3 times this then:
3x + x = 500
4x = 500
Divide both sides by 4:
4x ÷ 4 = 500 ÷ 4
x = 125
Meaning, the smaller box is 125g. The larger box is 3* this so:
3 * 125 = 375.
The small box is 125g and the larger is 375g.
Hope this helps!
