Hi

Please help to solve the question.

Siti opened a 2-kg packet of flour. She used 4/9 of the flour to make the pizza.
Then she used 2/7 of the remaining flour to make cakes.
Find the mass of the packet of flour that she had left.
Express your answer correct to 2 decimal places.

Thank you.

2 kg = 2000g
Remaining of flour = 5/9 x 2000
= 1111.11g
She uses 2/7 of the remaining to make cake
Remainign of flour left = 5/7 x 1111.11
= 793.65g
