Step-by-step explanation:
28 + 19 + 13 equal 60%
therefore 40% divided by 60% multiply by 160 gives number of chicks
Y = 3/2 t - 5/2 ; where t = 3
Substitute t by its value. the nearness of 3/2 to t denotes multiplication.
y = (3/2 *3) - 5/2
3 is a whole number. it is 3/1 in fraction form.
In multiplying fractions, simply multiply the numerator and the denominator.
y = (3*3 / 2*1) - 5/2
y = 9/2 - 5/2
Subtracting fractions: We can only subtract or add fractions if they all have the same common denominator. Since both fractions have 2 as denominator, we can proceed to subtracting its numerators.
y = (9-5)/2 *subtract numerators and place over the common denominator
y = 4/2 * simplify the fraction.
y = 2/1 or 2
