Give the number of significant figures in each number. Do at least half of the problems. Do as many more as you need to practice, but * indicates a required problem.
*a) 5000 |
b) 1.56 |
c) 92 | *d) 630 | e) 90100 | f) 40.7 |
*g) 0.0001 | *h) 0.0250 | i) 0.0607 | j) 300.5 | *k) 0.0450 | *l) 20.690 |
*m) 140700 | n) 2300 | *o) 0.008900 | *p) 6.020 | q) 20030 | r) 40 |
*s) | *t) | u) 4001 | *v) 800.0 | *w) 0.012 | x) 0.0100 |
Round off each of the following values to three significant figures
*aa) 72.65 | *ab) 14736 | ac) 0.00257 | *ad) 0.0030555 | ae) 647249 | *af) 2.9999 |
*ag) 6 | ah) 14.96 | *ai) 2996374 |
Do the following arithmetic
ba) add (in m) |
*bb) add (in g) |
*bc) add (in s) |
*bd) 67.6 x 1.30 = | *be) 41320/9.36 = | *bf) 0.0572 x 1563 = |
*bg) 9.36/3.12 = | *bh) 0.030 x 5208 = | bi) 4.300/132.7 = |
