Answer:

  60

Step-by-step explanation:

The ratio of sizes is ...

  blood cell / bacteria = 9×10^-6/(1.5×10^-7) = 90×10^-7/(1.5×10^-7)

  = 90/1.5 = 60

The red blood cell's length is 60 times that of the bacteria.

Hello from MrBillDoesMath!

Answer:

1.5,   1.6


Discussion:

The question is how to interpret 5/10 * 3.   Both multiplication and division have the same precedence but we proceed from left to right (doing the divison first)

5/10 * 3 = (5/10) * 3 = (1/2)* 3 = 3/2 = 1.5                  

Same approach for the second equation:

4/10 * 4 = (4/10) * 4 = 16/10 = 8/5 = 1.6


Thank you,

MrB
