(1+1+1+1+1)1+1 =52 =25
9+9+7*1=25
343 = 7 × 7 × 7
2.7778
7*(7 + 7) + 7/7 + 7/7 = 7*14 + 1 + 1 = 98 + 1 + 1 = 100
7 times 25 equals 175
(5 x 1) + 7 + 7 + 3 + 3 = 25
6 x 7 x 25 x 3 = 3150
1 x 1225, 5 x 245, 7 x 175, 25 x 49, 35 x 35, 49 x 25, 175 x 7, 245 x 5, 1225 x 1 = 1,225
1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175 and 525 Work: 3*5*5*7=525 Factors of 525 are: 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175 and 525
The GCF is 1.
You can make 37 using the numbers 1, 3, 5, and 7 by utilizing multiplication and addition. For example, you can calculate it as follows: ( (7 \times 5) + (3 \times 1) = 35 + 3 = 38 ). However, to achieve exactly 37, you need to adjust by using subtraction: ( (7 \times 5) + 1 - 3 = 35 + 1 - 3 = 33 ). This does not yield 37, indicating that it may not be possible to reach 37 using these specific numbers with standard operations.
6/7 - 6/25 = 6*(1/7 - 1/25) = 6*(25-7)/(7*25) = 6*18/(7*25) = 108/175
