To estimate (90 \times 0.4), you can round (0.4) to a simpler value. Since (0.4) is close to (0.5), you can estimate (90 \times 0.5), which equals (45). Thus, the estimate for (90 \times 0.4) would be slightly less than (45), around (36). A quick calculation gives (90 \times 0.4 = 36), confirming the estimate.
