Answer:

About #60# red blood cells will fit across the artery.

Explanation:

The small measurements in this question are what make it seem confusing at first. The word 'approximately' means it is not an accurate measurement.

Think about a similar question with easier values.
A tin has a diameter of #16# cm.
How many candles with a diameter of #2# cm can fit across it?

This is clearly a division #" "rarr16 div 2 =8# candles.

In the question given, it is also a division.

"How many times will #0.00075# fit into #0.0456?#"

#0.0456 div 0.00075 = (0.0456cm)/(0.00075cm)#

#= 0.0456/0.00075 xx 100000/100000 = 4560/75#

#=60.8#

About #60# red blood cells will fit across the artery.
