please help me with 168÷45​

we know that

168=(2^3)(3)(7)

45=(3^2)(5)

so

[tex]\frac{168}{45}=\frac{2^3\cdot3\cdot7}{3^2\cdot5}=\frac{2^3\cdot7}{3\cdot5}=\frac{56}{15}[/tex]

therefore

Convert to mixed number

56/15=45/15+11/15=3+11/15=3 11/15

therefore

the answer is

3 11/15 or 56/15

Part 2

Estimate te quotient using compatible numbers

so

168:45------------> 180:45=4do

Remember that

Compatible numbers are numbers that are easy to compute mentally
