00:07 Let's solve this problem together!
00:10 First, open the parentheses correctly.
00:13 The outer term multiplies each term inside the parentheses.
00:19 Remember, every whole number can be seen as having a denominator of one.
00:24 Don't forget, any number multiplied by zero is always zero!
00:28 Multiply the numerators together, and then the denominators.
00:33 Now, let's convert the fraction to a number with a remainder.
00:37 And that's how we find the solution. Well done!

Step-by-step written solution

1

Understand the problem

23(12+05)= \frac{2}{3}(12+0-5)=

2

Step-by-step solution

According to the distribution law rules, we will multiply both thirds by each term in parentheses:

23×12+23×023×5= \frac{2}{3}\times12+\frac{2}{3}\times0-\frac{2}{3}\times5=

Remember that any whole number can be written as a fraction with a denominator of 1, except for the digit 0.

Let's write the exercise in the following form:

23×121+23×023×51= \frac{2}{3}\times\frac{12}{1}+\frac{2}{3}\times0-\frac{2}{3}\times\frac{5}{1}=

We multiply numerator by numerator and denominator by denominator in each multiplication exercise.

Remember that when we multiply any number by 0, the result will be 0.

Therefore we get:

243+0103= \frac{24}{3}+0-\frac{10}{3}=

Let's solve the first fraction exercise, and simplify the remaining fraction to get the exercise:

8313=423 8-3\frac{1}{3}=4\frac{2}{3}

Final Answer

423 4\frac{2}{3}
