7*7 + 7 - 7 is one of many ways to do this.
To use four sevens to make 490, you can express it as follows: ( (7 \times 7 \times 10) - (7 + 7) ). Here, ( 7 \times 7 = 49 ), and multiplying by 10 gives you 490. The subtraction of ( 7 + 7 ) is not necessary for this specific equation, but you can also think of alternative ways to use four sevens and additional operations to reach the same result.
357 * 49 / 7 = 2499
49 metre because seven sevens = 49
42, 49, 56, 63, 70.....
To solve 49 x 9, you can use the distributive property. Break down 49 into 40 and 9, then calculate: (40 x 9) + (9 x 9) = 360 + 81 = 441. Alternatively, you can simply multiply directly: 49 x 9 = 441.

49 metre because seven sevens = 49
42, 49, 56, 63, 70.....
there are 343 sevenths in 49 not 7 because it says sevenths not sevens.
To solve 49 x 9, you can use the distributive property. Break down 49 into 40 and 9, then calculate: (40 x 9) + (9 x 9) = 360 + 81 = 441. Alternatively, you can simply multiply directly: 49 x 9 = 441.
Its easy 50=49+1 (7*7)=49 and (7/7)=1 50=(7*7)+(7/7)
There are seven sevens in fifty, as 50 divided by 7 equals approximately 7.14. This means that seven multiplied by 7 equals 49, which is the largest multiple of seven that fits into fifty. Thus, the whole number of sevens in fifty is seven.
Answer 6Here is why:7x7=49 which is 1 too many, so there are six sevens in 48 with a remainder of 6.
This can be written as 5x=49+2(-x). To solve this,simplify and solve. 5x=49-2x 7x=49 x=7
2/14 3/21 4/28 5/35 6/42 7/49
