Video Solution

Solution Steps

00:00 Solve
00:03 We want to convert from a number and fraction to just a fraction
00:07 We'll do this by multiplying the whole number by the denominator
00:10 and adding it to the numerator
00:14 We'll use the fraction formula in our exercise
00:31 Always solve multiplication and division before addition and subtraction
00:41 Make sure to multiply numerator by numerator and denominator by denominator
00:49 Each time we'll solve one multiplication and then continue
01:01 This is the fraction
01:07 Divide both numerator and denominator by 2
01:16 Break down 161 into 153 plus 8
01:24 Break down the fraction into whole number and remainder
01:32 And this is the solution to the question

Step-by-Step Solution

First, we'll convert the mixed fractions to simple fractions as follows:

23×7×3+23×3×2+12= \frac{2}{3}\times\frac{7\times3+2}{3}\times\frac{3\times2+1}{2}=

Let's solve the exercises in the fraction multiplier:

23×21+23×6+12= \frac{2}{3}\times\frac{21+2}{3}\times\frac{6+1}{2}=

23×233×72= \frac{2}{3}\times\frac{23}{3}\times\frac{7}{2}=

Since the only operation in the exercise is multiplication, we'll combine everything into one exercise and get:

2×23×73×3×2=46×79×2=32218 \frac{2\times23\times7}{3\times3\times2}=\frac{46\times7}{9\times2}=\frac{322}{18}

Answer

1789 17\frac{8}{9}
