Cross-multiply to see if the r ratio forms a proportion Select Yes if it forms a proportion and No it does not (3)/(8)=(2)/(5) No Yes

To determine if the given ratio forms a proportion, we need to cross-multiply and check if the products are equal.<br /><br />Cross-multiplying the given ratio, we have:<br /><br />$3 \times 5 = 8 \times 2$<br /><br />Simplifying the products, we get:<br /><br />$15 = 16$<br /><br />Since the products are not equal, the given ratio does not form a proportion.<br /><br />Therefore, the answer is No.
