Yuet Meng, 2unit x 20cents + 1 unit x 50cents => 1710cents 40cents unit + 50cents unit => 1710cents 90cents unit =>1710cents 1 unit => 1710cents/90cents 1 unit => 19 20 cents coins => 2 x 19 =>38 There are 38 20-cents coins.

As for me trial and error is not advisable for these kind of questions.... more time consuming but if u are comfortable then its OK ..as long u get the correct answer

Grouping seems most straightforward.

Yuet Meng, draw the comparison model and teach the child to find the value of 20cents coins and 50cents coins. That is what we teach them in school. That's how I came up with the answer above.

Another method Dif in value of 50¢ coins and 20¢ coins. 50-20== 30 cents diff $17.10÷30¢== 57 coins 20¢coins-2 units 50¢coins-1 unit 3units=57 1 unit= 19 2unit=38
