Multiplication of Decimal Numbers
好的，这个题目是要计算1.9乘以4.4。解这个问题，我们可以先不考虑小数点，将19与44相乘，然后再把小数点放回正确的位置。 所以，首先计算19乘以44： 19 x 44 --------- 76 (这是44乘以9得到的） +760 (这是44乘以1得到的，然后向左移一位） --------- 836 现在，由于原来的数中每个数都有一个小数位，所以总共有两个小数位。 将这个结果（836）变回带有两个小数位的数，也就是8.36。 所以，1.9乘以4.4等于8.36。
Multiplying Decimal Numbers
To find the product of 4.5 and 0.7, you simply multiply these two decimal numbers. Here's how you can do it: 4.5 × 0.7 ______ 315 ← (This is 4.5 multiplied by 7. Note that there are no decimal places here as if 4.5 were "45" and 0.7 were "7") ______ 3.15 ← (Since the original numbers had one decimal place each, the product should have two decimal places) So, the product of 4.5 and 0.7 is 3.15.
