jerry bought a piece of wood 5m long. he used 3/8 of the wood for a frame. and 1/5 to fix a door. he used the remainder of the wood on a kitchen cupboard. what fraction did he use on the cupboard
(3/8) * 5 = ?
(1/5) * 5 = ?
Add the two products above together. Subtract the sum from 5 meters.
thanks
You're welcome.
To find out what fraction of the wood Jerry used on the cupboard, we need to subtract the fraction used for the frame and the fraction used for the door from the total amount of wood.
Jerry bought a piece of wood that is 5m long.
He used 3/8 of the wood for a frame. To find out how much wood this is, we need to multiply the length of the wood (5m) by the fraction used (3/8):
3/8 * 5m = 15/8 m
He also used 1/5 of the wood to fix a door. Again, we multiply the length of the wood by the fraction used:
1/5 * 5m = 1m
Now, we need to subtract the fraction used for the frame and the door from the total length of the wood to find out how much remains for the cupboard:
5m - (15/8)m - 1m = 40/8m - 15/8m - 1m = 24/8m - 15/8m - 1m = (24-15-8)/8m = 1/8m
Therefore, Jerry used 1/8 of the wood on the kitchen cupboard.
