1/4 of 8/8 is 2/8. Add 2/8 to 5/8 = 7/8

Same answer as above...

0.625+0.25=0.875

I think the answer should be 7 - 8

1/4 = 2/8 5/8 + 2/8 = 7/8

Thanks to all who shared the answer.. 😊

100 × 30cm

Hi, Angie. Let me give you some hints. Step 1 104 - 8 to find the remaining tiles for the white rectangles. Step 2 Divide the remaining tiles from Step 1 by 2 because each white rectangle has 2 rows of tiles. You only want the tiles that surround the garden. Step 3 Take the divided number and add 1 tile at one end and 1 tile at another end. OR Add 2 tiles to your final answer in Step 2 to get the total tiles that surround the garden. Step 4 Take the answer from Step 3 and multiply it by 30 cm and then multiply it by 2 for the perimeter of the garden. Let me know if you don't understand any of the steps :)

I'm curious...looks like your ans is different from mine, Shaoyang Brandon

Shaoyang Brandon, is the answer 8700m? Actually I am not very sure.

Judy Low Your answer is correct except for the units.

Ah.... Yes. Misread the unit. Thanks for pointing out.

Nope. I can give you a hint. You don't need that four tiles grouped together because they don't cover the length or breadth of the garden. When those 4 tiles are removed, the remaining number of tiles represent the perimeter of the garden.

😅

3000m?

Thanks Brandon.. I only work till step 2, then not sure if 100 x 30 or 60 :(

100 x 30 is only half the perimeter of the garden. To get the entire perimeter, it will be 100 x 30 x 2 (same as 100 x 60). :)

Hi, Azlinah. This question involves two models: one at the start and the other at the end. You must draw the models to identify the additional units Ben and Chitra got from Abdul. This difference in units for Ben and Chitra will help you identify the amount if money for one unit. Which leads me to the second hint below. For each model drawing, the total number of units is 30 units or 10 units x 3 for divisibility purposes. :)

Hope it's correct.

Answer for b)

Thank you all for the solution..appreciate it..happy sunday :)
