Question

5.75 -3/7×63/4 +72/35÷1.44 solve this question ​

Answer 1

Answer:

3/7

Step-by-step explanation:

$=5.75 - \frac{3}{7} *\frac{63}{4}+\frac{72}{35}/\frac{1.44}{1}\\\\=5.75-\frac{3}{1}*\frac{9}{4}+\frac{72}{35}*\frac{1}{1.44}\\\\=5.75-\frac{27}{4}+\frac{72}{35}*\frac{100}{144}\\\\=5.75-\frac{27}{4}+\frac{1}{7}*\frac{20}{2}\\\\=5.75-\frac{27}{4}+\frac{1}{7}*\frac{10}{1}\\\\=\frac{5.75}{1}-\frac{27}{4}+\frac{10}{7}\\\\LCM~OF~1,4,7=28\\\\=\frac{161}{28}-\frac{189}{28}+\frac{40}{28}\\\\=\frac{161-189+40}{28}\\\\=\frac{-28+40}{28}\\\\=\frac{12}{28}\\\\=\frac{3}{7}$
