abruzzese [7]

Not sure about the weird echo in the question but I think we're being ask to evaluate

4 - 0.25g + 0.5h

when g=10, h=5

That's

4 - 0.25(10) + 0.5(5) = 4 - 2.5 + 2.5 = 4

Answer: 4

Yakvenalex [24]
Hi,

One example of proportion is 1:2=6:12 , with 1 and 12 being the extremes and 2 and 6 the means. In general, a proportion is an equality of two ratios, a:b=c:d, and a and d are called extremes while b and c are called means.

Hope this helps! If my answer was not clear enough or you’d like further explanation please let me know.
