there are 7/8 kilograms of salt in the kitchen.mrs Jackson use 2/15 of the salt when she was preparing dinner.how much salt did she useHere's how to solve the problem:Step 1: Find the amount of salt usedTo find out how much salt Mrs. Jackson used, we need to multiply the total amount of salt by the fraction she used:[tex]$\sf{(\frac{7}{8} kg) \times (\frac{7}{15}) =\frac{ (7 \times 2) } {(8 \times 15)} = \frac{14}{120} kg}$[/tex]Step 2: Simplify the fractionWe can simplify the fraction 14/120 by dividing both the numerator and the denominator by their greatest common divisor, which is 2:[tex]$\sf{\frac{14}{120} = \frac{(14 \div 2) }{ (120 \div 2)} = \frac{7}{60} kg}$[/tex]Final answer:Mrs. Jackson used [tex]$\sf\frac{7}{60}$[/tex] kilograms of salt.
