If $a:b = c:d$ , then which is true?

a $ad = bc$
b $ac = bd$
c $a+d = b+c$
d $a-b = c-d$

ব্যাখ্যা

From $a:b = c:d$ we get $\frac{a}{b} = \frac{c}{d}$ , and cross-multiplying yields $ad = bc$ . This means the product of the extremes equals the product of the means.

If $a:b = c:d$ , then which is true?

ad = bc

ac = bd

a+d = b+c

a-b = c-d
