Question

P5 section c paper 2. Please help. Thank you so much😊

Answer

Both earned the same salary, meaning the bars in the model are the same length. Find the LCM for the denominators in order to compare the difference in value of the savings with the units.

LCM for 7 and 5 is 35.

2X 5=10 (Nurul saves 10 units)

3×7= 21 (Lili saves 21 units)

21 – 10 = 11 (difference in units)

1540÷11=140 (value of 1 unit)

140×35 =4900 (Value of 35 units)

And is $4900

Both Nurul and Lili received the same salary

 

Nurul saving = 2/7 = 10/35

Lili saving = 3/5 = 21/35

21U – 10U = 11U

11U = 1540

1U = 140

Monthly salary = 35U = 4900$
