7 meters.100cm are in 1 meter,so 7x100=700 cm,with 84 cm left.it only needs 26 more meters to be at 8 meters
first, you must set up a similarity statement: 7 over 15 (or 7/15) equals n over 100 (100 because that's what percentages are out of; everything's out of 100%). now, we're trying to find out how much out of 100; that's what n is. n is a space holder for now. so, we're solving for the variable, n. so, we set it up like this: 7 n __ = ___ 15 100 then, we cross multiply; this means, we multiply the numerator (the number on top of the fraction) by the denominator (the number on the bottom of the fraction) of the other fraction. so, we multiply the 7 by the 100, and the 15 by the n. 7x100=700. 15xn=15n. now, the 700=15n because the fractions were equal, so now the equation is equal. then you solve algebraically for n. we want n all alone on the one side, so we divide 15n by 15. what you do to one side must also be done to the other. 700=15n ÷15 ÷15 ________ <- that's the equal sign 46.6667 = n so, 47=n. the answer is 47%. so, a quick review, 7 n __ = ___ 15 100 7x100=700. 15xn=15n. 700=15n 700=15n ÷15 ÷15 ________ 46.6667 = n 47=n the answer is 47%.
1x1000+7x100+6x10+0x1
1 = 100/100, therefore .75 is 75/100...... 7x100/100= 700/100. 700/100+75/100= 775/100.... make that into a smaller number and you'll have 31/5

784.3 =(7x100) + (8x10) + (4x1) + (3x1/10)700 + 80 + 4 + 3/10
62 704 =(6x10 000) + (2x1000) + (7x100) + (0x10) + (4x1)60 000 + 2000 + 700 + 0 + 4
7 meters =700 because 7x100=700 and 7 is equal to 700 centimeters.
80 788 =(8x10 000) + (0x1000) + (7x100) + (8x10) + (8x1)80 000 + 0 + 700 + 80 + 8
705 =700 + 0 + 57(100) + 0(10) + 5(1)(7x100) + (0x10) + (5x1)
703 =700 + 0 + 37(100) + 0(10) + 3(1)(7x100) + (0x10) + (3x1)Alternatively, you can leave out the placeholders (0, zeros)
7 meters.100cm are in 1 meter,so 7x100=700 cm,with 84 cm left.it only needs 26 more meters to be at 8 meters
