1 inch = 12 miles
so 6 1/2 inches (or 6.5 inches) = 6.5 * 12 = 78 miles <===
learners of Agriculture: 34/58
semplify it
divide by 2
34 > 17
58 > 29
they are prime numbers, so can't be semplify anymore
17/29 will do Agriculture
in percentage we have a proportion:
17 : 29 = x : 100
x = (17 * 100) / 29 = 1700 / 29 ≅ 48,62
Answer:
