A pile of sand has a weight of 90kg the sand is put ina small bag a median bag and a large bag in a ratio 2:3:7 work out the weight. Of the sand in each bag

Make an equation

2x+3x+7x=90

5x+7x=90

12x=90

x=90/12

Now multiply 90/12 times 2 to get the weight of the small bag-15kg

Then multiply 90/12 times 3 to get the weight of the median bag-22.5kg

Lastly multiply 90/12 times 7 toget the weight of the large bag-52.5kg

Small=15kg

median=22.5kg

large=52.5kg
