Answer:
No, (false). The question I assume was:
Step-by-step explanation:
1. Multiple: 3 * 8 = 24
2. Multiple: <em><u>The result of step No. 1:</u></em> * 1 = 24 * 1 = 24
3. Conversion a decimal number to a fraction: 8.1 = =
a) Write down the decimal 8.1 divided by 1: 8.1 =
b) Multiply both top and bottom by 10 for every number after the
decimal point. (For example, if there are two numbers after the decimal
point, then use 100, if there are three then use 1000, etc.)
=
Note: is called a decimal fraction.
c) Simplify and reduce the fraction
4. Multiple: 3 * 8.1 = =
Multiply both numerators and denominators. Result fraction keep to lowest
possible denominator GCD(243, 10) = 1. In the next intermediate step the
fraction result cannot be further simplified by canceling.
In words - three multiplied by eighty-one tenths = two hundred forty-three
tenths.
5. Compare: <em><u>The result of step No. 2 </u></em>vs <em><u>The result of step No. 4</u></em>: = 24 vs =
vs
=
vs
=
vs
= 240 vs 243 = No
