00:03 Let's write division as a fraction, and keep the last division
00:21 Let's break down 4 into factors 2 and 2
00:30 Division is also multiplication by the reciprocal
00:36 Let's reduce what we can
00:43 Note to multiply denominator by denominator and numerator by numerator
00:52 Let's calculate 13 divided by 10

Step-by-Step Solution

Firstly, let's rewrite the exercise as a fraction:

13×2x4a:5z= \frac{13\times2x}{4a}:\frac{5}{z}=

Next, we'll factor out the 4 from the denominator of the first fraction into a smaller multiplication exercise and invert the second fraction to create a multiplication exercise:

13×2x2×2×a×z5= \frac{13\times2x}{2\times2\times a}\times\frac{z}{5}=

We'll now reduce the 2 in the numerator and denominator of the first fraction:

13×x2×a×z5= \frac{13\times x}{2\times a}\times\frac{z}{5}=

We'll then multiply the two multiplication exercises:

13×x×z2×a×5=13xz10a \frac{13\times x\times z}{2\times a\times5}=\frac{13xz}{10a}

Finally, we divide 13 by 10 to get:

1.3xza 1.3\frac{xz}{a}

Answer

1.3xza 1.3\frac{xz}{a}
