Chloe Loh, your diagram has represented the problem correctly. Now consider: if you subtract 2174 from the total,what would the amount be? And what total in terms of percentage would you have w/o the 2174? Equate those 2 quantities and work out what 22% represents.

Is there any word after the word "of"? "After Nora spent 22% of"

Your kid has made a careless mistake. Instead of writing 78 in the box, ur kid wrote "72". Guess because of this, ur kid could not solve it. :)

Use a box in place of x. Draw a diagram to illustrate the relationship between the numbers so that the child understand. There's only one variable so you should be able to solve it with one equation.

Saw a "short cut" method for such qn: 58 - 4 = 54 8 - 5 = 3 54 รท 3 = 18 pupils

My humble opinion that it's important for the child to understand the rationale of the method n not apply without understanding.

A diagram would be clearer to a young child. The short cut method is also derived from the equation i.e. 8x + 4 = 5x + 58.
