Ian has 12.2 ounce bottle of ketchip. He uses 1/20 of the ketchup every time he has a buffalo burger How many ounces of ketchup
1 answer:
If Ian uses 1/20 of the ketchup 4 times, this is equal to 4/20, or 
.
can be simplified to 
, which means we need to work out of 12.2
is equivalent to 20%, which as a decimal is 0.2
0.2 x 12.2 = 2.44 - however, this is how much he has used, and we need to figure out how much is left.
12.2 - 2.44 = 9.76
So, Ian has 9.76 oz remaining :)

Step-by-step explanation:
- The equation given is
- Divide the leading term of the dividend by the leading term of the divisor:
- Multiply it by the divisor:
-
Subtract the dividend from the obtained result:
- Divide the leading term of the obtained remainder by the leading term of the divisor:
- Multiply it by the divisor:
- Subtract the remainder from the obtained result:
- Divide the leading term of the obtained remainder by the leading term of the divisor:
- Multiply it by the divisor:
- Subtract the remainder from the obtained result:
- Since the degree of the remainder is less than the degree of the divisor, then we are done.
- Therefore,
