(a) 0.121

Work Step by Step

Multiply (43.998$\times$ 0.00552) S.F rule: the zeros at front don't count. 0.00552 has 3 S.F, which is the least S.F. (43.998$\times$ 0.00552)=0.24286896... round the number at the end. 0.24286896...$\div$ 2.002=0.121313... The least S.F is 3, so we round the number as 0.121
