• Why had the equation become 4*6=g*3 ?

• Each guest ate 3 truffles, so the total number of truffles eaten is the number of guests times 3 or g*3.
Akshay bought 4 boxes of truffles, each box contained 6 truffles, so the total number of truffles bought is 4*6. Now, the total number of truffles eaten is the same as the total number of truffles bought, so 4*6 = g*3. Now you can figure out how many guests there are.
• What are truffles?
• Truffles are chocolate 🍫🍫🍫. Yummy yummy
• do you use an x for a times sign?
• In this grade it means "times", but later on "x" sometimes means an unknown number along with any other letter.
• At why did he do g times 3 i know what it means but it has nothing to do with the answer it is just supposed to be 4 times 6 divided by 3.
• Sal shows at the basic algebraic expression necessary to solve this problem, that the number of total truffles (4 X 6) is equal to three times the number of total guests at the party (3 X G). The point is that dividing the total number of truffles (24) by the number eaten by each guest (3) gives you the total number of guests. But a simpler, more basic way of thinking about it is, What number of guests multiplied by three (to represent the amount of truffles each eats) would give the total number of truffles (twenty-four)? Division and multiplication are basically complementary, reverse operations similar to addition and subtraction.
• i got it first try
• wheres the multiplication sign on the keyboard
• There are different ways of showing multiplication on your keyboard. You can use just an x, like 6 x 2. You can also use an asterisk, like 6*2. Or you can use parentheses, like 6(2).
