You changed the sign but you didn't flipped the fraction, 2/3 over. It should be 55km * 3/2 instead of 55km * 2/3
It's 55km ÷ 2/3h or 55km x 3/2h not 55km x 2/3hIshani
The 'x' sign in the 2nd line was changed from the '÷' sign, but the person did not flip the fraction '2/3'.
When divide, you must "flip" the fraction then can multiply.If your answer is 36 and 2/3 then still round of to 3 S.F for what?Owen here.
The error is: Transition mistake. 55km ÷ (1/2h +1/6hr)= 55km ÷ 2/3hr (not multiply)
You changed the sign but did not change the fraction . It should be 55km * 3/2 and not 55km * 2/3 .
You round up to 3SF already why still put the answer as 36 2/3...Your that two slanted lines should put at the last answer you get BTW ur supposed to do like 55km x 3/2 since u have to flip it
If 55km is divided by 2/3, it should be 3/2 when flipped to multiplication.
After you added 1/2 to 1/6, it should be 2/3 but when you change the divide to multiply, the fraction should be flipped so it should be 55km*3/2h
1/2 + 1/6 = 3/6 + 1/6 = 4/6 = 2/3This part is correct. However there was a divide sign before this thus he/she should have inverted the fraction to 3/2.Therefore,55 ÷ 2/3 = 55 x 3/2 =82.5
You didn't flip the fraction when u changed the ÷ sign to x signCARELESS! :P
You didn't flip the fraction :D after you change the divide sign to multiply sign :D :D :D
The Error: 55 km ÷ 2/3 h ≠ 55 km * 2/3 hIt Should be: 55 km ÷ 2/3 h = 55 km * 3/2 h
The person changed the divide sign to times sign but did not flip the fraction.
Change sign must flip
We must flip the fraction when we change the (÷) to (x), so 55km ÷ 2/3h = 55km x 3/2h.
The person should invert the fraction when he changed the divide to multiply. He should leave his final answer as 3 significant figures too.
He did not flip the fraction when he changed the divide sign to the multiplication sign.
you did not use the reciprocal of the fraction.
Thanks to all or I wouldn't know the mistakes.I didn't flip it. darn.
You didn't flip the fraction after you changed the divide sign to multiply sign
