Answer:

111/20 = 5.55

Step-by-step explanation:

He used a total of 1  3/4 and  3  4/5 salt.

Convert both these mixed numbers into fractions.

=> 7/4 + 19/5

Take the LCM of the denominators

=> 35/20 + 76/20

Add the numerators

=> 111/20 = 5.55

He used a total of 111/20 or 5.55 kgs of salt.

melomori [17]
<span>The organic farm uses 3/7 of the land to grow potatoes
=> 2 /5 of the land to grow spinach
=> x = the fraction of the land to grow tomato plants.
The easiest wat to get the answer is convert first the fraction to decimals
=> 3/7 = 0.43
=> 2/5 = 0.4
=> x = ???
=> 0.43 + 0.4 = 0.83
=> let the whole land = 1
=> 1 – 0.83
=> 0.17, the remaining land left for tomato plants
Convert now to fraction
=> 17/100</span> (Approximately)

YOu can also use this method:
=> 3/7+ 2/5 +x = ?
Find the LCM
=> 3/7 + 2/5 = 29/ 35
=> 35/35 - 29 / 35
=> 6 / 35, the remaining land
