the outside measurements of a picture frame are 12 and one tenths( 1 over 10)cms and 6 and 3 over 4 cm.the frame is 1 over 2 cm wide.
what is the area of the picture?
thankyou
you need to learn how to type fractions better.
i suppose you mean the outside measurements of the frame are cm by cm. and the frame is 1/2 cm thick (that is, its border around the picture is 1/2 cm)
Now
and
so the length of the picture will be cm. (since we subtract 1/2 cm at the top and bottom for the picture frame)
and the width of the picture is cm (since we subtract 1/2 cm from both sides for the picture frame)
So the area of the picture is:
can you take it from here? work out what are in the brackets first
yes
yeswould b. be 6 and 1 over 4?
i needed to know what fraction of an hour is 50 minutes. now i know that 1 hour = 60 minutes. so (1/60)hour = 1 minute. multiply both sides by 50, we get: (50/60)hour = 50 minuteshey how did u work out da time to be 5 over 6?sorry i didnt understand...........
yes. (with cm^2 as the units)
