NOW LETS CONVERT IT INTO SI UNIT THE CM TO METRE . 1CM IS EQUAL TO 10 ^MINUS 3 METRE THEREFORE IF WE CONVERT 15CM TO METRE WE WILL GET 0.015 METRE . now let's multiply GIVE US 0.015*13is equal to 0.0195 now let's rond off to two decimal place it will be 1.6*10to the power minus 2
You just put two numbers that you can multiply to get the number and when you came divide anything else in the number then you circle it and that's one of the numbers
