Q. 9. Using distributivity, find(i) {57×(12−3)}+{57×125}
Apply Distributive Property: First, apply the distributive property to combine the terms with a common factor of (57).(57)×(−123)+(57)×(125)=(57)×((−123)+(125))
Add Fractions: Now, add the fractions inside the parentheses.(−123)+(125)=(122)
Simplify Fraction: Simplify the fraction (122) to its lowest terms.(122)=(61)
Multiply by Common Factor: Multiply the simplified fraction by the common factor (57).(57)×(61)=(5×67×1)
Perform Final Multiplication: Perform the multiplication to get the final answer.(7×1)/(5×6)=7/30
