the rounded calculations should resemble those you have already worked out in question 2.
a) 37x219
b) 8.7 x 54
c) 66.34x 25.84
d) 0.1672 x 985.5
e) 65x349
f) 840.7 x 0.0155
g) 503x850
h) 0.6199x74.51
1) 0.0488x272.07
estimate the answer to each of the following multiplications by first rounding each number to
1significant figure.
a) 24x18.4
b) 8.234x5.0123
c) 9642 x 237
d) 0.123x862
e) 0.734x 26.382
