Answer for screen readers
The ratios equivalent to ( 5:8 ) are ( 15:24 ) and ( 10:16 ).
Steps to Solve
-
Convert Ratios to Fraction Form
Convert the given ratios to their fractional forms:- For ( 5:8 ), the fraction is ( \frac{5}{8} ).
- For ( 1:2 ), the fraction is ( \frac{1}{2} ).
- For ( 15:24 ), the fraction is ( \frac{15}{24} ).
- For ( 10:16 ), the fraction is ( \frac{10}{16} ).
-
Check Equivalent Ratios
To check if two fractions are equivalent, cross-multiply and compare:- Compare ( \frac{5}{8} ) and ( \frac{1}{2} ):
( 5 \times 2 = 10 ) and ( 1 \times 8 = 8 ) (not equivalent). - Compare ( \frac{5}{8} ) and ( \frac{15}{24} ):
( 5 \times 24 = 120 ) and ( 15 \times 8 = 120 ) (equivalent). - Compare ( \frac{5}{8} ) and ( \frac{10}{16} ):
( 5 \times 16 = 80 ) and ( 10 \times 8 = 80 ) (equivalent).
- Compare ( \frac{5}{8} ) and ( \frac{1}{2} ):
-
Summary of Results
The ratios equivalent to ( 5:8 ) are ( 15:24 ) and ( 10:16 ).
The ratios equivalent to ( 5:8 ) are ( 15:24 ) and ( 10:16 ).
More Information
