When we divide a number \(D,\) the dividend, by another number \(d,\) the divisor, we obtain the quotient \(Q.\) Obviously, the dividend is the product of the quotient and the divisor: \(D=dQ.\)
In our case, \(1.5=5(0.2+x)\) or \(1.5=1+5x,\) from which \(5x=0.5\), and finally, \(x=0.5/5=0.1.\)
Answer B.
