Studdy Solution
STEP 1
1. We are tasked with finding of .
2. We need to determine which of the given calculations correctly compute this value.
STEP 2
1. Understand the meaning of .
2. Evaluate each given calculation to determine if it correctly computes of .
STEP 3
Recall that means or .
STEP 4
Evaluate the first calculation: .
- Calculate :
$ 900 \times \frac{7}{100} = 900 \times 0.07 = 63
\]
- Calculate :
900 \times 1\% = 900 \times 0.01 = 9
\]
9 \times 7 = 63
\]
- Evaluate the fraction:
$ \frac{63}{63} = 1
\]
This calculation does not yield of .
STEP 5
Evaluate the second calculation: .
- Convert to a decimal:
$ 7\% = 0.07
\]
- Calculate :
$ 900 \div 0.07 = 12857.14
\]
This calculation does not yield of .
STEP 6
Evaluate the third calculation: .
- Calculate :
$ 900 \times 0.01 = 9
\]
- Multiply by :
$ 9 \times 7 = 63
\]
This calculation correctly yields of .
STEP 7
Evaluate the fourth calculation: .
- Calculate:
$ 900 \times 0.07 = 63
\]
This calculation correctly yields of .
STEP 8
Evaluate the fifth calculation: .
- Convert to a decimal:
$ 0.07\% = 0.0007
\]
- Calculate:
$ 900 \times 0.0007 = 0.63
\]
This calculation does not yield of .
The three correct calculations for finding of are:
1.
