Nope. A lizard is a reptile.

My thought is let the child know what classify as amphibian. e.g. Amphibians spend their lives in the water and on land. (Since lizards can't survive in water, they are not amphibian .)

Unless they're marine iguanas? Are iguanas lizards or amphibians?

Lizards are reptiles as they have scales. Amphibians have moist skins like salamanders and frogs.

180-53-53=74 The 53 degrees is repeated because it is overlapped when the triangle is folded.

Ok wait, I get it now.. You were looking at the angle on the straight line, after you unfold the folded part..

BNC1 is 180' (angle on straight line) MNC1 = MNC = 53' (the overlap when unfolded)

This is not the first time we encounter such a question; we have seen this qn in P5 but we still forgot that this is how it can be solved. Thanks once again!

Note that 1/100 + 99/100 = 1; 2/100 + 98/100 = 1; 3/100 + 97/100 = 1; and so on. 1. You need to "count" how many such pairs. 2. The last pair is 49/100 + 51/100, and so there are ... pairs. 3. Plus the 50/100 that is not accounted for. :)

So should be 99 ?

1/100 to 49/100 + corresponding 99/100 to 51/100 = 49 pairs = 49. Take whole number 49 + 50/100 (0.5) = 49.5

Hi! I think since Tom can assemble half of a toy when Jerry can only assemble a quarter means that Tom can assemble a toy twice as fast as Jerry. So, if Tom assembled a fifth of a toy, Jerry had only assembled half of what Tom had, thus, Jerry had assembled half of a fifth which is a tenth. I hope my answer helps.. :)
