Ex 3.4, 4 A tailor has 15 3/4 metres of fine silk. If making one kurta requires 2 1/4 metres of silk, exactly how many kurtas can he make? First, we convert both mixed fractions into normal fraction Now, Total length of silk = 15 3/4 metres = 15+3/4 = (15 Γ— 4 + 3)/4 = (60 + 3)/4 = πŸ”πŸ‘/πŸ’ m And, Length of 1 kurta = 2 1/4 metres = 2+1/4 = (2 Γ— 4 + 1)/4 = (8 + 1)/4 = πŸ—/πŸ’ m Now, Number of kurtas that can be made = (π‘‡π‘œπ‘‘π‘Žπ‘™ π‘™π‘’π‘›π‘”π‘‘β„Ž π‘œπ‘“ π‘ π‘–π‘™π‘˜)/(πΏπ‘’π‘›π‘”π‘‘β„Ž π‘œπ‘“ 1 π‘˜π‘’π‘Ÿπ‘‘π‘Ž) = πŸ”πŸ‘/πŸ’Γ·πŸ—/πŸ’ = 63/4 Γ—4/9 = 63/9 Γ—4/4 = 7 Γ— 1 = 7 Thus, total 7 kurtas can be made
