5 × 1 +
0 × 1//10 +
3 × 1/100 +
7 × 1/1000 in decimal from
The expression 7 × 100 + 6 × 10 + 5 × 1 + 0 × 1/10 + 3 × 1/100 + 7 × 1/1000 can be simplified as follows:
7 × 100 = 700
6 × 10 = 60
5 × 1 = 5
0 × 1/10 = 0
3 × 1/100 = 0.03
7 × 1/1000 = 0.007
Adding all these values together, we get:
700 + 60 + 5 + 0 + 0.03 + 0.007 = 765.037
Therefore, the decimal form of the expression is 765.037.

0 × 1/1000
4 × 100 + 2 × 10 + 4 × 1 + 7 × 1/10 + 7 × 1/100 + 0 × 1/1000 can be simplified as follows:
4 × 100 = 400
2 × 10 = 20
4 × 1 = 4
7 × 1/10 = 0.7
7 × 1/100 = 0.07
0 × 1/1000 = 0
Adding all these values together, we get:
400 + 20 + 4 + 0.7 + 0.07 + 0 = 424.77
Therefore, the decimal form of the expression is 424.77.
