Answer:
0.004
0.08
Explanation:
To round a decimal number to one significant figure, first locate the first non-zero digit and draw a vertical line after it.
Look at the next digit:
- If it is 0, 1, 2, 3 or 4, keep the previous digit the same.
- If it is 5, 6, 7, 8 or 9, increase the previous digit by one.
0.00426 = 0.004 | 26 = 0.004
0.07999 = 0.07 | 999 = 0.08
