Jemima filled one fourth of a barrel with compost on Saturday. Then she filled the remaining space with 4,200g of compost on Sunday. How many kilograms of compost are in the barrel

5.6kg

Step-by-step explanation:

Since Jemima filled one fourth of a barrel with compost on Saturday, then the remaining space will be:

= 1 - ¼ = ¾

Since the remaining ¾ space is filled with 4200g of compost, then the compost in the barrel will be

¾ × x = 4200g

0.75 × x = 4200g

0.75x = 4200g

x = 4200g/0.75

x = 5600g

Since 1000g = 1kg

5600g = 5600/1000 = 5.6kg

There is 5.6kg of compost in the barrel.
