⅞ kg of salt was in the kitchen.
Mrs. Sabe used 2/15 of the salt when preparing dinner.
How much salt did she use?
This doesn't make any sense
Just did this, look for the earlier post of this
To calculate how much salt Mrs. Sabe used when preparing dinner, you'll need to multiply the amount of salt in the kitchen (⅞ kg) by the fraction representing the amount she used (2/15).
To do this, you'll first need to convert the fractions to a common denominator. The denominator (or the bottom number) of the fraction determines how many equal parts the whole is divided into. In this case, the denominators are 8 and 15, respectively.
To find the common denominator, you can either multiply the two denominators together (8 * 15 = 120) or find the least common multiple (LCM) of the two numbers. In this case, the LCM of 8 and 15 is also 120.
Now that you have the common denominator, you can convert the fractions:
⅞ kg can be written as (8/8) * ⅞ = 56/8 kg
2/15 can be written as (8/8) * 2/15 = 16/120
Next, multiply the two fractions:
(56/8) * (16/120) = (56 * 16) / (8 * 120) = 896 / 960
To simplify the fraction, you can divide both the numerator and denominator by their greatest common divisor (GCD), which in this case is 32:
896 / 960 = (896 ÷ 32) / (960 ÷ 32) = 28/30
Finally, convert the fraction back into a mixed number or decimal, if desired. In this case, 28/30 can be simplified to 14/15 or approximately 0.9333 kg.
Therefore, Mrs. Sabe used approximately 0.9333 kg of salt when preparing dinner.
